Greater contact with humans, who passed on the disease is likely the primary reason why this occurred.
<h3>What do you mean by population bottleneck?</h3>
Specified, widespread violence or purposeful culling, human population planning, and other human actions such as famine, earthquakes, floods, fires, disease, and droughts can all cause population bottlenecks. Population bottlenecks can also occur owing to genetic bottlenecks. As a result, a smaller population with less genetic variety is left to transmit genes to future generations of offspring through sexual reproduction. Such events can limit the variation in a population's gene pool. Only when gene flow from another group happens or very slowly over time as random mutations take place, genetic diversity rises, but it still remains lower.

Answer:
b. ex post facto or quasi-experimental.
Explanation:
An ex post facto search is done when a researcher cannot manipulate one of the variables such as sexual behavior or smoking (as described in the question), ie this type of research is done when it is not possible to manipulate the independent variables as they already arrive ready for research. Ex-post fact research deals with variables that are unmanipulated in nature. Quasi-experimental research can also be done for this same situation.
